It depends on how much you flex and turn tightly, You can trim the bumper a lot if all you do is drive on the road..if you go offroad, body lift, leveling coils, or a 4 inch suspension will get you enough flexing room.
Thanks for the help guys, been away from comp for a couple days it was killing me to know the answer! Anyway, I will get those badboys on and get a pic up by the end of the week... Manik grill guard going on tomorrow, gonna look sweet!
Got a 96 Stock with 33x12.50's. They work fine except for a little rub when you turn hard either way. Just a small drawback for some nice looking tires.
